Hi Chris & Acee,
I have explained my concerns the previous mails. In order to avoid unnecessary overlap, I supports the adoption of the drafts like follows:
- both drafts are adopted at the same time keeping draft-li-dynamic-flooding focus on the centralized solution and draft-cc-lsr-flooding-reduction on the distributed solution.
- draft-li-dynamic-flooding can keep on refining the centralized solution without mentioning distributed solutions.
- draft-cc-lsr-flooding-reduction can keep on refining the distributed solutions. For the signaling which can be shared by the two modes, the draft can indicate the distributed solutions reuse the signaling defined in draft-li-dynamic-flooding without defining new signaling. 
- both drafts change the draft names to reflect different solutions without causing confusion.


Thanks & Regards,
Zhenbin (Robin)

主题: [Lsr] WG Adoption Call for draft-li-lsr-dynamic-flooding-02 + IPR poll.


Hi Folks,

We are starting a 2 week adoption call on draft-li-lsr-dynamic-flooding-02.

The aim of this document is to describe the problem space and standardize a
way to signal dynamic flooding information. It does not standardize any
specific algorithm for flooding topology creation.

Authors please respond indicating if you are aware of any IPR related to
this work.

We also have another draft (draft-cc-lsr-flooding-reduction-01) that started
as a distributed flooding topology algorithm and morphed into that plus
competing ideas on signaling of flooding topology information. The intent
after adoption of draft-li-lsr-dynamic-flooding-02 is two-fold. One, the WG
can discuss adding any signaling ideas from this work to the adopted
signaling draft (with proper attribution given as appropriate), and two, for
the authors of draft-cc-lsr-flooding-reduction-01 to publish a new document
without the signaling portion and instead focus on their flooding topology
algorithm. This new focused document can be considered in parallel along
with the other algorithm work that has been proposed.

Flooding topology creation is seen as a hard problem for which we don't
expect a one-size-fits-all solution. Taking the steps outlined above will
help us move forward on the solutions.

Thanks,
Chris & Acee.
LSR WG Chairs.
